Vaccines

WHO/Stephen Chernin

Vaccination is the most effective way to prevent infection and severe outcomes caused by influenza viruses.

Development and production of influenza vaccines, planning for their supplies and use as well as provision of other respective health care resources are essential components of a comprehensive seasonal and pandemic influenza response.

For more than 50 years, WHO has been collaborating with scientists and policy makers on a global scale to develop a unified approach to manufacturing, testing and regulatory oversight of influenza vaccine development as well as their efficient use and distribution.
